If the balance between repulsion and attraction is lost, particles will agglomerate. Attraction is the force that attracts objects. Particles are uniformly dispersed among each other because of the influence of electric charge.Īlong with the electrostatic repulsive force, an attractive force also acts. The stable existence of many micelles results in an emulsion. When an emulsifier is added, hydrophilic groups are placed on the water side and hydrophobic groups on the resin side, forming spherical aggregates. Resin and water do not mix well together, so they separate when mixed normally.Įmulsifiers consist of hydrophilic groups that are compatible with water and hydrophobic groups that are compatible with resin. Since organic solvents are not used, these emulsions are environmentally friendly and are now the mainstream method used.Īs an alternative to solvent-based emulsions, they are widely used in housing construction materials.Įmulsifiers play a major role in emulsions. Sick building syndrome, which has become a problem, is one of the causes of organic solvents.Īcrylic resin is emulsified and dispersed in water. However, organic solvents also have problems with air pollution and adverse health effects. ![]() Because of its water resistance and paintability, it was widely used for the exterior walls of houses.Good elongation when applied, and easy to use as a coating.Excellent water resistance and adhesion, and resistance to rain and wind.Acrylic resin and organic solvent blend wells, and emulsions are easier to make than water-based emulsions.Solvent-based emulsions have the following advantages: Uses of Acrylic EmulsionsĪcrylic emulsions are available in two types: organic solvent-based and water-based.Īcrylic resin is emulsified and dispersed in an organic solvent such as thinner. In addition, since acrylic resins can be freely designed, various types of emulsions have been developed for applications other than housing construction materials. They have excellent gloss, weather resistance, stain resistance, and are often used in coatings for housing construction materials.Īcrylic emulsions are often emulsified and dispersed in water. ![]() An Acrylic Emulsion is an acrylic resin which is emulsified and dispersed in a solution.
